CHICKEN BROODER.

Application filed. January 31, 1928. kSerial No.`2\50,801.

The present invention has reference to broeders, and more particularly tothe heating system thereof, the primary object of the invention being te provide means whereby the chicks housed in the brooder will not be subjected te the direct heat of thev heating results in the injuringl of the weaker chicks. Y

A still further object of the invention is to provide a bi'ooder wherein the heating plant may be controlled from a peint exteriorly of the brooder to the end that the interior of the broeder will not be. chilled as the heating plant is being attended to. j

lilith the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the. cembination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention erein disclosed, may be made within the scope of what is claimed, without departing "iro-iii the spirit of the invention.

Referring to the drawings: 1 Figure 1 is a vertical sectional view through a broeder constructed in accordanceV with the invention.

Figure 2 is a transverse sectional view through a portion of the brooder, one end of the l eater being shown in section.

Figure 3 is a vertical sectional view through the central portion of the heater.

Figure 4e is a sectional view taken. on line 4 4 of Figure 1.

Referring te the drawings in detail, the brooder proper is indicated generally by the numeral 5 and includes spaced walls 6 and 7 respectively, deiining a dead air space to insrf te the interior ofthe brooder against cold. 'lli-e gei'ieral shape of the brooder proper forms no part of the invention'and it is within the scope. of this invention to provide circular, rectangular or other shape broeders with a heating plant forming the essence of the invention.

As clearly shown by Figure 1, the heater includes a substantially rectangular section 8 having an upstanding portion 9 disposed intermediate the ends of the heater proper, the

portion' being disposed at apoint within the broodei to thoroughly heat the interior `of the broeder.

Communicating withene end of the section 8 is a section 10 formed with an upvvardly .inclined end portion v11 that extends to a point above the ground surface on which the brooder is resting, it being understood that the heater in this invention is buried in the ground surface, and the floor of the brooder,

which is indicated at 12,'and which may be` dirt oijothe'r. suitable material, rests directly on the heater te be heated by the heater.

lAnlinelined section 13` connects with thev opposite. end of the section 8 and also extends to a point above the ground surface and beyondy the side wall of the brooder so vthat an attendant may have easy accessthereto, to the end that the fuel may be added te the heater with facility. v

Closuresll close the outer ends of the inclined portions 11 and 13 of the heater and are pre-vided with draft openings 15, there being provided Vclosures 16 for controlling the draft through the openings 15.

Vsitliin the heater are mounted pivoted grate bars 17 which are normally inclined as shown by Figure 1 of the drawings so that air may pass under the grate bars to insure the burning of the fuel. supported thereon.

At the outer ends of the grate bars are vertical regulating bars 18 that have hand grips 19 at their upper ends, the bars 18 being shown as passing through openings in the inclined portions of the heater. VFormed on the bars are teeth 20 that engage one edge of the openings to which they extend, so that the grate bars may beV regulated vertically to accomplish the purpose ef the invention.

The upstanding portion 9 of the heater is substantially 'large and is provided with a closure 21 so that the device may be readily cleaned should it become clogged with soot,

or need repairing.r v

The chimney is indicated by the numeral 22 and communicates with the upstanding portion 9, it being'understoed that the chimney passes through the upper portion of the brooder to carry off the smoke and objectionable fumes from the heater.

Frein the` foregoing it will be seen that due tothis construction, the floor of the brooder will be thoroughly heated to keep the chicks feet warm, and the heat from the upstanding portion, as well as the heat arising from the floor, will of course maintain the proper tem peralure in the brooder so that the chicks will not crowd.

I claim I l. A brooder includln a housine a tubun Y @a lar heater under the housinT and under the o v u b a Hoor of the housing, inclined end portions formino a part ot the heater the inclined end portions havingl exposed outer extremities,A

closures for normally closing' the outer eX- tremities7 gratos in the heater on Which the fuel is supported, and a chimney communieating with 'the heater for carrying fumes from the heater.

2. A broeder including` a housing;7 having a Iloor, an elongated heater embedded in the yground surface under the tloor, said heater having` inclined ends extendingabove the ground surface at the sides of the housing, hinged closures for closing* the inclined ends, pivoted grate members Within the heater and von which 'fuel is supported, and a sinokestaclr extending through the housing and communicating with the heater. i

3. A broeder including a housing, a heater extending transversely under the housing and embedded in the ground surface on which the housing` rests, said heater h avingr inclined upper ends extending` above the ground surface, grates Within the heater7 and a chimney neeaees extending` through the housing and communieating;v with the heater. i

il. A broeder including a housing, a heater including' rectangular body portion extending'V under the broeder and having upwardly disposed end portions7 pivoted grate bars posed end portions through which material may bejed to the heater, grates in the ,tubu-V lar heater on which iuel is adapted to be supported, and a chimneyA including an enlarged upstandinn' portion and extending Vthrough the housing` and communicating With the heater.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.
